Northlake, Texas electricity: Oncor wires, 3 split ZIP codes to check
Northlake is one of the fastest-growing towns in the AllianceTexas corridor, and whether a new home there can shop for electricity depends on which utility built the street.

In short: Northlake's competitive homes are on Oncor's wires, but almost none of them carry a Northlake mailing address in ERCOT's data, so this page leans on ZIP-level counts. Our data can't give a reliable Northlake-wide figure: ERCOT lists only a handful of homes with a Northlake mailing address, because Northlake homes mostly use Justin (76247), Trophy Club or Roanoke (76262) and Argyle (76226) postal addresses, and the ZIP codes around Northlake show roughly half as many competitive meters as Census households. That gap fits co-op service (CoServ or Tri-County) on many streets. Check your exact address.

Common questions about electricity in Northlake
Is Northlake electricity CoServ or Oncor?
Both serve the area. Oncor-delivered addresses can choose a retail provider; CoServ and Tri-County Electric Cooperative members cannot. ZIP 76226 shows a ratio well below 1 between competitive meters and Census households, which is what co-op service looks like in our data. Ask your builder or check a bill.
Does the Town of Northlake provide electricity?
No. The town's utility billing office handles water, sewer and trash only; electricity comes from Oncor plus a retail provider, or from a co-op such as CoServ, depending on the street.
What is the average electricity rate in Northlake?
A typical Northlake home on Oncor's wires using 1,000 kWh a month was looking at a median of 13.4¢ per kWh among 170 fixed-rate Power to Choose listings on October 19, 2026; at 500 kWh the median was 14.1¢. Delivery alone is 6.8673¢ per kWh plus $4.06 a month. Your price depends on usage and plan terms.
Why does my Northlake home have a Trophy Club address?
ZIP 76262 is shared. In ERCOT's data, 48% of its 10,507 competitive residential meters use Trophy Club as the postal city and almost none use Northlake. Mailing city and city limits are different things; the service address decides which utility serves you.
Who do I call in Northlake when the power goes out?
Oncor for Oncor-delivered addresses, not your retail provider. Co-op members call their co-op.
